Folded sheet product

ABSTRACT

The present invention discloses a folded sheet product comprising a folded sheet having a first set of folds and a blister strip attached to a segment of said sheet. A stiff portion may be provided at a corner segment of the sheet.

FIELD OF THE INVENTION

[0001] The present invention relates to folded sheet, products, whetherin a folded or unfolded condition.

BACKGROUND OF THE INVENTION

[0002] It is known from European Patent No. EP-A-288 472 to provide afolded sheet product comprising folded sheet with a first and second setof concertina folds, which sets of folds are transverse to one another.Provision of such folded sheets with stiff portions at segments of thesheet in the region of diagonally opposite corners of the sheet providesa means of easily unfolding and refolding the sheet material.

[0003] Manufacturers of pharmaceuticals must supply product informationwith the products they sell, in particular with pre-packaged productsthat are sold without prescription. This product information isimportant so that the purchaser is aware of the manner in which theproduct should be used, the dosage, any possible side effects of takingthe product and what to do in an emergency.

[0004] This type of product information is generally enclosed in thepackaging of the product in the form of a leaflet. A problem associatedwith such products, is that consumers rarely read the productinformation set out on the leaflet. Also, the leaflet often remainswedged in the packaging and is disposed of with the packaging once theproduct has been removed therefrom. Furthermore, as a result ofautomated and high speed packaging processes the wrong leaflet can-besupplied with a product.

[0005] Manufacturers of other products such as shampoos, moisturecreams, cosmetics, instant coffee, artificial sweeteners, seeds forgardening etc, often use blister strips to distribute samples of theirproducts for advertising purposes. A disadvantage of this arrangement isthat only a limited amount of product information, if any at all, can bedisplayed on blister strips.

[0006] It is an aim of preferred embodiments of the present invention toovercome problems associated with the prior art, whether mentionedherein or otherwise.

SUMMARY OF THE INVENTION

[0007] Generally, unless otherwise stated herein, the phrase “sheet” ishereby defined as a material that takes folds at which is can beunfolded without the folds disappearing and refolded. It may be paper,or a paper-like material such as plastics sheet on which books arecommonly printed, or may be very thin card or any other suitablematerial. It is conceivable that the sheet material may be stiff cardexcept at the folds, e.g. very thin stiff cards interconnected by paperor cloth, but this is deprecated as not allowing full realisation of theadvantages of the invention.

[0008] The present invention provides a folded sheet product comprisinga folded sheet having a first set of folds and a blister strip attachedto a segment of said sheet.

[0009] Unless otherwise stated herein, the phraseb “blister strip” meansa packaging arrangement comprising a cover sheet and a substrate. Thecover sheet comprises one or more indentations in which a product can becontained. The substrate is attached to the cover sheet so as to coverthe openings of the indentations *and thereby seal the product therein.The substrate usually comprises a foil or film material that can beeasily ruptured or pierced to release the product by pushing theexterior surface of the indentation inwards. However, the substrate maybe such that it is less easily ruptured. In this case, the substrate andor the cover sheet must be cut or torn in the region of the indentationto release the product.

[0010] The blister strip may be attached directly or indirectly to thefolded sheet.

[0011] Suitably, the blister strip is located at ort near a cornersegment of the sheet. If the sheet comprises a single row of segments,the blister strip is suitably located at an end segment of the row.

[0012] The blister strip may be attached to a segment of the sheet byany suitable means, for example, by an adhesive. Heat sealing techniquesmay be used to attach the blister strip to a segment of the sheet.

[0013] The substrate of the blister strip may be attached to the foldedsheet. Alternatively, the substrate of the blister strip may be providedby a segment of the sheet.

[0014] Suitably, the segment of the sheet to which the blister strip isattached comprises perforations. The perforations are arranged tofacilitate removal of the product from the blister strip. Suitably, theperforations correspond in location with the opening(s) of theindentation(s) of the cover sheet of the blister strip. The perforationsmay be substantially X shaped.

[0015] Alternatively, or in addition, the segment of the sheet to whichthe blister strip is attached may comprise one or more cut out sections,which one or more cut out sections suitably correspond in location withthe opening(s) of the indentation(s) of the cover sheet of the blisterstrip.

[0016] The one or more perforations and/or cut out sections may definean opening in the sheet having any suitable shape for example, circularor rectangular. Suitably, the one or more openings defined by the one ormore perforations and/or cut out sections has or have dimensions whichcorrespond substantially with the dimensions of the one or more openingsof the indentations of the blister strip. A single cut out sectionand/or perforated region may be provided for each indentation of theblister strip. Alternatively, a single cut out section and/or perforatedregion may be provided for a plurality of indentations of the blisterstrip.

[0017] Suitably, a folded sheet product in accordance with the presentinvention further comprises a stiff portion. Suitably, the stiff portionis attached to a segment of the folded sheet. The stiff portion may beprovided by the blister strip.

[0018] Alternatively, the stiff portion may be-separate from the blisterstrip. If the stiff portion is separate from the blister strip, thestiff portion may be attached to the blister strip or the stiff portionmay be at a separate segment of the sheet.

[0019] The substrate of the blister strip may be attached to the stiffportion. Alternatively, an edge of the stiff portion may be attached-toan edge of the blister strip.

[0020] Suitably, the stiff portion is substantially the same size and/orshape as the blister-strip.

[0021] An edge of the stiff portion may be attached to an edge of theblister strip by any suitable means. For example, the stiff portionand/or the blister strip may have a marginal flange extending along aportion of the edge for attachment therebetween. The marginal flange mayextend along a major portion or substantially the full length of theedge.

[0022] If the marginal flange extends from the stiff portion it may beattached directly to the blister strip. Alternatively, the marginalflange of the stiff portion may be attached indirectly to the blisterstrip. The blister strip may also comprise a marginal flange, to whichthe marginal flange of the stiff portion is either directly orindirectly attached.

[0023] If the marginal flange extends from the blister strip it may beattached directly to the stiff portion. Alternatively, the marginalflange of the blister strip may be attached indirectly to the stiffportion.

[0024] The marginal flange may be attached to the stiff portion and/orthe blister strip be any suitably means, for example, by means of anadhesive.

[0025] The marginal flange may comprise a line of weakness, e.g. aperforated tear line, extending along the length thereof to facilitateremoval of the blister strip from the stiff portion.

[0026] Suitably, a fold line is provided between the marginal flange andthe edge of the stiff portion and/or the edge of the blister strip fromwhich it extends.

[0027] Suitably, the blister strip can be arranged to lie flat againstthe stiff portion.

[0028] The marginal flange may be an extension of the stiff portionand/or the blister strip, which may form another stiff portion.Alternatively, the marginal flange may be provided by a tab which isattached to the edge of the stiff portion and/or the blister strip.

[0029] Once an edge of the blister strip has been attached to an edge ofthe stiff portion, one or more of the free edges of the blister stripmay be fastened to a corresponding edge of the stiff portion byfastening means in order to maintain the blister strip folded againstthe stiff portion. Suitably, the fastening means temporarily fasten theone or more free edges of the blister strip against the stiff portion.The fastening means may, be re-usable, so that the blister strip may beunfastened and then refastened in its folded condition against the stiffportion.
